The list of most conductive metals includes silver, copper and gold. The conductivity standard of metal is based on silver, which is the most conductive of all metals.Know More
Conductivity is defined as the ease with which an electric charge or heat passes through a metal. A conductor gives little resistance to the flow of electric current or heat, which means that a conductor allows an electric charge to flow freely through it. Conversely, an insulator resists the flow of electricity. Ceramics, wood and plastics are considered insulators. Thermal conductivity refers to the ease with which heat passes through a conductor or insulator. Electrically conductive metals typically are also thermally conductive.
From most to least conductive, the top 10 metals are:
The conductivity of all metals is compared to that of silver. On a scale of zero to 100, where 100 represents the most conductive, silver ranks 100. In addition to being a strong electrical conductor, silver does not make sparks easily. It is used in electrical components like contacts and circuits. It is important to note that gold rates a 76 on the conductivity scale. Popular belief suggests that gold is a better conductor than silver, but facts prove this assumption to be false.Learn more about Chemistry
The major defining feature of metals is that electrons flow relatively freely between atoms in any object composed of two or more metal atoms, whereas electrons around nonmetals are more tightly bound to their respective nuclei or within individual chemical bonds. This results in other significant features of metal, particularly their high thermal and electrical conductivity. A large majority of known elements are metals.Full Answer >
Metals are opaque, lustrous natural elements that are effective in conducting electricity and heat. The majority of metals used in everyday applications are ductile and malleable and are usually denser than other elemental substances.Full Answer >
Metals are malleable and ductile because they are made of hexagonal and cubic packed structures that can be moved by applying force to them. When force is applied, the atoms slide from one plane past atoms in a different plane.Full Answer >
Metals that are potentially toxic are known as heavy metals, which include mercury, lead, iron, bismuth, cadmium and thallium. Arsenic, which is a non-metal but exhibits metallic properties, may also result in poisoning.Full Answer >
